Emerald Ash Borer Information
have watched TV, listened to a radio, or read a newspaper
in the past month then you will be familiar with the Emerald
Ash Borer (E AB ). This is the latest invasive pest to come
into Illinois and threaten our tree population.
in Michigan a few years ago, this insect has no natural predators
and has been eating its way across the Midwest, being found
in Illinois earlier this summer. Current locations where
its presence has been verified include Kane County, Evanston
and Wilmette along the lake shore.
The Department of Public
Works has received numerous calls about the Ash Borer, |and
has investigated many insects residents thought might be
the EAB .
The Emerald Ash Borer is rather distinctive in
appearance, the adult stage looking
very much like a small,
green grass hopper more than a beetle or June bug. Communities
and tree lovers are very concerned about the possibility
of the EAB gaining a foothold here as over 20% of the trees
in the Chicago area are Ash trees. This insect could wrought
as much or more damage on neighborhood trees as the Dutch
Elm Disease did in the 1960's and 1970's.
Below are photo's
showing the Emerald Ash Borer in both its larval and adult
phase. If you believe you have found an Emerald Ash Borer,
